Hello! I am ready to implement a smart contract for passive arbitrage with flash loans and a simple front end, because I have experience in creating secure DeFi solutions and understand how to avoid wallet substitution and ensure full control for the owner.

Hello. I have experience building a complex deposit smart contract on Solidity. For simplicity of demonstration, I created a regular web interface with Bootstrap. Fast, simple, and understandable. To connect to the network (where the smart contract runs), MetaMask is usually used.
Ready to discuss details

Hello, Mykyta! 🌟
My name is Semen, I am a developer with experience in creating DeFi applications, specifically arbitrage contracts with flash loans on DEX exchanges. I watched the video at the link, understood the logic of passive arbitrage through flash loans, and also noted the issue with fake wallets in the contract. I am ready to develop a clean contract for you with a frontend for local deployment and management (deposit, withdrawal, auto-withdrawal).
📋 Implementation Plan:
Smart Contract:
I will develop a contract in Solidity for arbitrage on DEX (for example, Uniswap/PancakeSwap).
I will use flash loans (Aave or dYdX).
I will add wallet verification: funds will only go to your wallets (specified in the contract).
I will implement deposit, withdrawal, and auto-withdrawal functions.
Frontend:
I will create a simple frontend in React for local deployment.
I will add an interface for:
Depositing into the contract (specifying the amount, confirmation via MetaMask).
Withdrawing funds (manual or auto-withdrawal).
Viewing balance and transaction history.
Security:
I will check the contract for vulnerabilities (reentrancy, overflow).
I will add an access modifier (only your wallet will be able to manage the contract).
📋 Frontend (React):
For local deployment, I will add a simple React application with a connection to the contract via ethers.js. You will be able to deposit, withdraw funds, and set up auto-withdrawal through the browser with MetaMask.
💰 Cost and Timeline:
Development of the contract and frontend: 90,000 UAH (10-14 days).
Testing and security audit: 10,000 UAH.
Total: 100,000 UAH (within your budget).
❓ What’s Next:
Specify which DEX exchanges to use (Uniswap, PancakeSwap, etc.).
Provide a wallet for managing the contract.
I will start after agreement.
I look forward to your feedback! 🚀
Best regards, Semen 😊

Hello
We reviewed the video — everything is clear, ready to collaborate.
We are the IcornA team, specializing in the development of crypto projects: smart contracts, DeFi, automation, front-end.
We have real experience, we work quickly and results-oriented. Ready for long-term collaboration.
Ready to:
Conduct an audit and fix the logic
Create a working contract with flash loan
Make a simple front-end (local launch)
We are waiting for the code — we can start today!
Thank you for your time.

Great, thank you for the details and the video 📹
I watched it and here’s how I see the task:
🔍 What needs to be implemented:
Audit and analysis of the smart contract
Review of the source code (in the video) — calculations, arbitration logic, flash loans.
Identification of "fake" parts — especially withdrawals to external wallets.
Development of your own smart contract
A real working contract for DEX arbitration (Uniswap, Pancake, etc.).
With support for flash loans (Aave/Uniswap).
Gas optimization, security, tests.
Simple web interface (frontend)
Local launch (without deployment)
Interface: deposit, withdrawal, view status/balance/logs
Ability to specify wallets for withdrawal (or auto-withdraw)
(Optional) Telegram notifications about actions or profits
💰 Budget
We fully fit within the specified budget up to 100,000 UAH
I suggest in stages:
Stage 1 (audit + test contract) — 15–20k
Stage 2 (final contract + tests) — 30–35k
Stage 3 (frontend + auto-withdraw + local launch) — 20–25k
The remainder — for QA, minor adjustments, and support
⏳ Deadlines
10–14 days for the entire implementation
(you can start with MVP for tests)
👨💻 I work with Solidity, Hardhat, ethers.js, React, Next.js. With experience in DeFi, DEX bots, and automation.
📥 Send the source code of the contract and an example of the arbitration logic, if available — ready to get started!

Hello!
I have reviewed the project description and video, and I understand the general idea: to implement a smart contract that uses flash loans for arbitrage between DEX exchanges, with the ability to manage deposits/withdrawals through a simple front end.
